possession of "any territorial advantages or preferential or exclusive concessions in impairment of Chinese sovereignty or inconsistent with the principle of equal opportunity in Manchuria"; and that Japan and Russia "engaged reciprocally not to obstruct any general measures common to all countries which China might take for the development of the commerce and industry of Manchuria." This distinction between the special interests of the contracting parties and the interests of China herself as well as of foreign nations generally is essential to clear understanding of a situation which subsequently attracted much attention. From the time of the opium war (1857) to the Boxer rising (1900) each of the great Western powers struggled for its own hand in China, and each sought to gain for itself exclusive concessions and privileges with comparatively little regard for the interests of others, and with no regard whatever for China's sovereign rights. The fruits of this period were: permanently ceded territories (Hong-Kong and Macao); leases temporarily establishing foreign sovereignty in various districts (Kiaochow, Wei-hai-wei and Kwang-chow); railway and mining concessions; and the establishment of settlements at open ports where foreign jurisdiction was supreme. But when, in 1900, the Boxer rising forced all the powers into a common camp, they awoke to full appreciation of a principle which had been growing current for the past two or three years, namely, that concerted action on the lines of maintaining China's integrity and securing to all alike equality of opportunity and a similarly open door, was the only feasible method of preventing the partition of the Chinese Empire and averting a clash of rival interests which might have disastrous results. This, of course, did not mean that there was to be any abandonment of special privileges already acquired or any surrender of existing concessions. The arrangement was not to be retrospective in any sense. Vested interests were to be strictly guarded until the lapse of the periods for which they had been granted, or until the maturity of China's competence to be really autonomous. A curious situation was thus created. International professions of respect for China's sovereignty, for the integrity of her empire and for the enforcement of the open door and equal opportunity, coexisted with legacies from an entirely different past. Russia endorsed this new policy, but not unnaturally declined to abate any of the advantages previously enjoyed by her in Manchuria. Those advantages were very substantial. They included a twenty-five years' lease--with provision for renewal--of the Liaotung peninsula, within which area of 1220 sq. m. Chinese troops might not penetrate, whereas Russia would not only exercise full administrative authority, but also take military and naval action of any kind; they included the creation of a neutral territory in
